เครื่องวัดเสียงแบบพกพา DeltaOHM รุ่น HD2020
รายละเอียดสินค้า :
• The 1000 Hz frequency allows calibrating sound level meters with any frequency weighting (LIN, A, B, ...), without applying any correction factor.
• The generated sound pressure level is indipendent of atmospheric pressure: you don’t need to adjust the value according to static pressure over a wide range of values.
• The calibrator can be conveniently used both in laboratory and in the field. The 114 dB sound level allows performing calibrations even in high background noise environments.
• Its simplicity of use allows even unskilled staff to use it.
